SQL 2005 CLR stored procedure to use VSS lib

Posted on 2006-07-14

I want to write a procedure which will delete some records from my tables
Each of these records will contain a path to a folder in VSS that also needs to be deleted.
So I decided to go for CLR procedure to access VSS with the help of Microsoft.VisualStudio.SourceSafe.Interop.dll

I may add here that I'm using CLR code for the first time.
So, I found this one on how to create a CLR procedure.
http://www.sqlteam.com/item.asp?ItemID=21927
I got PrintToday working fine.

Now deleting the records from table is also fine. These separate procedures are in place.

Now problem is that, I cannot add reference to the VSS dll in my above mentioned project.
So how I'm going to connect to VSS?
I tried copying the dll to my project's bin. Still it doesn't show up in the add reference dialog box.

I'm using VS 2005.

Is it not possible? Am I doing something wrong in my project selection?

Hi puranik_p,
Have you looked into using sp_cmd to delete the files?

Cheers!

I don't know what is sp_cmd.
I couldn't find it in BOL.

One update...
I opened the csproj file in notepad and added the reference to VSS lib.
Now, it's showing up in references and I can also code using intellisence.
What's more, it even builds successfully.
But when I 'Deploy', I get this error...
Error      1      Assembly 'microsoft.visualstudio.sourcesafe.interop, version=5.2.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a.' was not found in the SQL catalog.      CSharpPart1

Here's the complete code I've written...

using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using Microsoft.VisualStudio.SourceSafe.Interop;


public partial class StoredProcedures
{

    [Microsoft.SqlServer.Server.SqlProcedure]
    public static void PrintToday()
    {
        // Put your code here
        try
        {
            //'— The SourceSafe INI file.
            string iniVssPath = "C:/CLRVSS";

            //'— The SourceSafe User ID/Password.
            string cVSSUserName = "Admin";
            string cVSSPassword = "";


            VSSDatabaseClass vssLib = null;
            vssLib = new VSSDatabaseClass();
            vssLib.Open(iniVssPath, cVSSUserName, cVSSPassword);

            VSSItem VSS_Item = vssLib.get_VSSItem("$/Test", false);
            VSS_Item.Destroy();

            SqlPipe p;
            p = SqlContext.Pipe;
            p.Send("success");
        }
        catch
        {
            SqlPipe p;
            p = SqlContext.Pipe;
            p.Send("error");
        }
    }
};

Any help?

Datrias,
with xp_cmdshell, I can delete windows folders not the VSS ones.

Actually, it would be this:

string iniVssPath = @"C:\CLRVSS";

    or this

string iniVssPath = "C:\\CLRVSS";

Here is a thought about that error:

It turns out that you can force SQL Server to use FX libraries that are not on the approved list. Deploying user code that uses these through Visual Studio produces...

It appears that there is an "approved" list, and maybe the VSS interop library isn't on it.

TheLO,
From the post, it doesn't take me anywhere near to the solution.
I'm very very rusty with .Net nowadays. Primary focus being on SQL Server.
I opened the GAC, and VSS dll is already there.
Anything else in the world that I can do get this solved?

So, this didn't help:

CREATE ASSEMBLY foo FROM 'c:\types\foo.dll

Copying 'System.Runtime.Remoting' to c:\types produces another "Could not find assembly". Eventually I put my assembly in the FX lib directory so it can resolve everything and set the permission_set to unsafe.

I tried that. I got this...
Warning: The Microsoft .Net frameworks assembly 'microsoft.visualstudio.sourcesafe.interop, version=5.2.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a.' you are registering is not fully tested in SQL Server hosted environment.

>>Eventually I put my assembly in the FX lib directory
I don't know what is a FX lib directory.
Any clue?

1. ALTER DATABASE [MyDatabase] Set TRUSTWORTHY ON
2. CREATE ASSEMBLY VSS FROM 'C:\Microsoft.VisualStudio.SourceSafe.Interop.dll'
WITH PERMISSION_SET = UNSAFE
3. Now, in the add reference window, this dll is visible.
4. Build and Deploy from buid menu option

The catch is, there are 3 permission levels for create assembly
1. SAFE - default mode - cannot access extrnal resource (files/folders)
2. EXTRNAL_ACCESS - can access extrnal resource (files/folders) bu not COM dlls.
3. UNSAFE - can do everything in the world including reference to COM dlls.

The naming of these options...SAFE, UNSAFE doesn't convey much.
But that's true for many microsoft things. :o(

Now my next challange is to deploy it on the db server where this VSS dll is not available.

Quite a learning anyways.

Thanks TheLO for the time you spent on this.

Yeah, I did see the UNSAFE permission set, but I was struggling to figure out what the FX library meant.  It was a wild goose chase, I guess.
